I have to call this data that comes from Signaturit. The problem is that they are grouped in a kind of family or groups. I'm using Swagger to build the API.

Name of the parameteres I have to work with

And I can't call those parameters because JS tells me "ReferenceError: created_at is not defined". That error is normal because I'm trying to give it a property that doesn't exist.

But I need to call those parameters and I can't change the way the platform sends me the data.

Code:

params: {
        'document[created_at]': req.swagger.params.document[created_at].value,
         created_at: req.swagger.params.created_at.value,
         type: req.swagger.params.type.value,
}

Thanks
